The FIFA World Cup Round of 16 features a significant European showdown as Portugal, led by veteran Cristiano Ronaldo, takes on Spain, spearheaded by young star Lamine Yamal.

Spain enters the match as a -105 moneyline favorite to win within 90 minutes, according to DraftKings Sportsbook. Portugal is listed as a +280 underdog.

Portugal's path to this stage included a near elimination in their Round of 32 match against Croatia. After falling behind 1-0, Cristiano Ronaldo converted a penalty to equalize, and Gonçalo Ramos scored in stoppage time to secure a 2-1 victory. VAR later disallowed a Croatian goal that would have tied the score.

Portugal's tournament performance has been inconsistent, marked by a 5-1 win over Uzbekistan, but also draws against Colombia and DR Congo. They finished second in Group K.

Spain, after an initial draw against Cape Verde, found its rhythm and won Group H. The team showcased a strong defense, shutting out opponents in their knockout-stage opener with a 3-0 victory over Austria. Mikal Oyarzabal scored twice in that match.

Spain, ranked No. 3 by FIFA, has maintained four clean sheets in the tournament. Their strategy involves dominating possession, utilizing midfield versatility, and leveraging Yamal's attacking play. The 19-year-old Yamal has adapted to the physical demands of the game, often acting as a decoy to create opportunities for teammates like Oyarzabal, who leads Spain with four goals.

The tactical matchup is expected to be a tight contest. Spain's defense, particularly against Ronaldo's central attacking role, will be a key factor. Players like Bruno Fernandes and Joao Neves will be tasked with controlling the midfield against Spain's Dani Olmo and Pedri.

Given the familiarity between the two sides, a low-scoring game is anticipated, making an under 2.5 goals bet a possibility. Analysts suggest Spain is peaking at the right time, while Portugal's recent form has been less convincing. Spain is predicted to score first and hold on to advance to face the winner of the United States-Belgium match in the quarterfinals. Recommended bets include Spain on the first-half moneyline at +150 and Spain to advance at -200.
